Thank you both beretgascon and wOOdy for your answers.

I found exactly what i was looking for on the last link you gave me, wOOdy.
www.newsscriptphp.com has exactly the functions i want.

When reading in their text/helpfiles i understand that you should be able to place this inside an iFrame?? So if a place an iFrame inside a placeholder it shouldn´t be a problem as i can see it. Am i right?

I have also sent a mail to my webserver provider and asked if it´s ok to install the necessary files on the server.

Best regards // Kalle
